I just finished my run of Dragon Knight Saga with an unarmed female warrior.
She didn't start out on Nightmare, but it was tough enough. I never really played Nightmare much until this time, and now I've realized something - the expansion is so much better if you up the difficulty to Nightmare after reaching level 40 or so. (Change from Normal to Hard at about 30.)
In Normal, I breezed through a lot of the expansion, it wasn't challenging much at all, but wow, was I surprised at how much more exciting and dangerous things got on Nightmare mode.
The fights with Bellegar's monsters were snoozes on Normal, but I actually ran out of time with the last one once. The boss fight against him was also surprisingly dangerous. And even though I was a level higher than Ygerna at the end, and even though I had over 1550 HP, she did crazy damage to me, and I died like four times fighting her.
